Abstract: PURPOSE:To prevent image forming property for a near substrate from deterioration and peripheral light from reduction by changing a certain air interval in the 1st group under the state having approximately linear relation to the delivered distance of the 1st group in accordance with the delivery of the 1st group. CONSTITUTION:The titled optical system is constituted of the 1st group 1 having a negative focal distance and the 2nd group 2 having a positive focal distance arranged on the image field side of the 1st group 1. At the time of zooming, the interval between the 1st and 2nd groups 1, 2 is changed. The 1st group 1 is constituted of the pre-group having at least one negative lens and one positive lens and a post-group arranged on the image field side of the pre-group and having negative refractive force. At the time of focusing from an infinite range to a close range, the delivering speed of the post-group is larger than that of the pre-group and the shown formula (f1F is the focal distance of the pre-group, fw is the focal distance of the whole system at a wide angle end and (d) is the air interval between the whole group and the post-group at the infinite substance) is satisfied.

Filed: 1984-06-04
Abstract: PURPOSE:To sequentially obtain two or more same emission spectra as those emitted from two or more light sources using a single lamp source by secularly varying the emission spectra at turning off, using two or more kinds of phosphor with different persistence characteristics. CONSTITUTION:The inner wall of a glass tube 1 is coated with a phosphor layer 2 whose pricipal components are magnesium germanate calcium tungstate. A mercury atom 3 sealed in the glass tube 1 is used as a cathode and a graphite electrode 4 formed on both end of the glass tube 1 is used as an anode. Arc discharge is generated between these electrodes. The phosphor layer 2 applied on the inner wall of the glass tube is stimulated by the emission spectra caused by the discharge and the phosphors with the respective two peak wavelengths of red and blue are generated. The former has the longer persistence time as compared with the latter and continues emission for a preset period of time after turning off. As a result, the emission spectra can cyclically be varied by blinking this fluorescent lamp using a blinking signal with a proper frequency.

Abstract: PURPOSE:To remove readhesion of denaturized substance of photoresist caused by etching so as to prevent wire breaking of the second aluminum wiring by coating a titanium-tungsten film further on a interlayer insulation film so as to use it as a mask when forming a through hole. CONSTITUTION:After removal of a photoresist film 4, a titanium tungsten film 5 is coated and a photoresist film 6 in through hole pattern is patterned. Next, the titanium-tungsten film 5 and the nitride film 3 are etched by anisotropic dry etching to the conduction where the nitride film is still left on a first aluminum wiring 2, and then with the titanium-tungsten film 5 as a mask, the left nitride film 3 is etched until it reaches the first aluminum wiring 2. Hereby, such a trouble disappears that the denaturized substance of the photoresist by overetching readheres much and remains even after through hole formation, and breaking of the second aluminum wiring can be prevented.

CONSTITUTION: The respective reference positions of a couple of a transmitter and a receiver disposed in the sea and a threshold regarding a distance are written in a reference position data memory 13 and a natural sound ray between the reference position of the transmitter and the reference position of the receiver is computed by an arithmetic processing part 17 by using data on a field of acoustic velocity and written in a natural sound ray data memory 14. Every time when an acoustic signal between the transmitter and the receiver is observed, the reference positions being nearest to the positions of the transmitter and the receiver at the time of observation and located within the range specified by the threshold are selected.  An amplitude of a variation in a propagation time of an acoustic wave caused by a positional slippage of each of the transmitter and the receiver is determined by the arithmetic processing part 17 on the basis of the selected reference positions and the positions of the transmitter and the receiver. Based on the determined amplitude of the variation in the propagation time of the acoustic wave, the propagation time of the acoustic wave observed by the transmitter and the receiver is corrected.
